Required Knowledge

C / C++ Experience

EOSIO based blockchains execute user-generated applications and code using WebAssembly (WASM). WASM is an emerging web standard with widespread support of Google, Microsoft, Apple, and others. At the moment the most mature toolchain for building applications that compile to WASM is clang/llvm with their C/C++ compiler. For best compatibility, it is recommended that you use the EOSIO toolchain.

Other toolchains in development by 3rd parties include: Rust, Python, and Solidity. While these other languages may appear simpler, their performance will likely impact the scale of application you can build. We expect that C++ will be the best language for developing high-performance and secure smart contracts and plan to use C++ for the foreseeable future.

Linux / Mac OS Experience

The EOSIO software supports the following environments:

• Amazon 2017.09 and higher
• Centos 7
• Fedora 25 and higher (Fedora 27 recommended)
• Mint 18
• Ubuntu 16.04 (Ubuntu 16.10 recommended)
• Ubuntu 18.04 LTS
• MacOS Darwin 10.12 and higher (MacOS 10.13.x recommended)

Command Line Knowledge

There are a variety of tools provided along with EOSIO which requires you to have basic command line knowledge in order to interact with.
